I have worked with a CO-OP for the last 5 years. In my current position i am a work night leader. who has the responisbility of the CO-OP and the bikes that are built on my night of service every week.
Since i am in Colorado, Gears are valuable, When we rehab we keep the double or triple on it and if some one wants to make it a 1x? they can pay the extra for the open shop time to do the conversion.
We rehab alot of older mountain Bikes and we keep them as functional and as much of their original components as possible, while replacing with something that is either same quality level or better or about the same and newer.
It is up to the work night leaders to guide the volunteers for what the CO-OP wants them to do. we will build 1x or Single/Fixie's but they are usually either already converted or we get in a bare frame that would work good for the fixie.
As for the things that are being done, I can understand the Fixie/Single speed but i have no interest in owning one.
